you can change a loctite cog/lockring. i've done so a few times, just takes more force than one with grease-- and not enough to hurt anything. we're not talking j-b weld here, it's loctite.
i'd only avoid loctite if you change your cogs often, but the majority of street riders don't-- loctite is fine if you're swapping a cog once a year or something.
that said, i used grease on the last two cogs i installed. i probably won't use loctite in the future, but not because there's anything wrong with it, but rather because i only have grease at home which works.
